up-side-down coil???

Damn! You're right! I never thought of that!

 

Model T's have that crazy Big Coil "Box" and it doesn't really compare to a "Normal" coil. the wires do come out the side on most of them that I have seen

 

Someone should have told GM about the horizontal coil mounting. The mounted millions of coils that way. Could it be that the China made coils are defective in oil fill?

I thought maybe this was going to be about Austin Coil...

 

"Upside down" coils are wrong ??? I guess it's too late to tell that to GM ....

Ha! These replies are classic!! So if they need to be upright here in America, should they be up-side-down in Australia? They are on the other side of the world after all...

 

I had a car that overturned one day and kept running until the oil ran out and then the engine sized, . I guess this proves for a fact that you can't run a coil upside down.

 

the coil should be fine. unless its leaking the oil out...

 

And the oil only runs out when the seal holding the oil in becomes defective and allows a leak...

 

Now, that shit is funny!!!

 

Every FE and Y block ford from the factory had the coil mounted in a horizontal position. The farmall tractors have a horizontal mounted coil. I seen lots of chevy sixes with the coil mounted upside down. Im calling this a myth just like the myth about concrete killing a battery. Ive had folks swear that if you hauling something with a exhaust driven turbo charger and you dont cover the exhaust with duct tape the turbo will turn and burn out the turbo,s bearings. it cant happen you gotta have a large volume of air flowing for that to happen. If every exhaust and intake valve was wide open maybe? Old Wolf

 

A datum point...I just went through the coils section of a circa 1953 Echlin book and then a circa 1972 one. Numerous coils, OEM and universal. Brackets are suggested for non-stock mountings of the replacement coils, brackets are offered for all the universal and hotroddish coils. Some stockers like the locking MOPAR ones almost have to mount horizontally, Ford FH ones gotta mount factory style with secondary down, others potentially mountable anyway you can screw the mount to something.
Several coils in each catalog and in every category are noted as oil-filled, presumably meaning that the others are filled with something else.
NOWHERE is there any sort of notation on orientation limits, here or in a similar set of listings from Standard...

 

Some of these answers are as funny as the "You know your getting old when..." ones.

 

This myth is due to poor estimates about how long the battery sat (without being recharged)
Have you noticed that when you ask someone how long its been since an old car was started, their estimate is way off?

 

Mine's been mounted up side down for more years than I can remember, no problems at all.
